Since then I was curious, which myrmica sp. it is exactly, cause I wanted to call her by her full name
I figured the picture I took was not enough, so today while she fed her kids I got to take a sharp closeup in good light.

If there is any extra information that could help, just tell me. I'm very curious which one exactly it is.

Definitely looks like Myrmica to me, but you should know that this genus can't be properly identified without microscopic examination of a worker.

If you enjoy my expertise and identifications, please do not put wild populations at risk of disease by releasing pet colonies. We are responsible to give our pets the best care we can manage for the rest of their lives.
